The value of diagnosing the peripheral type of lung pathological changes by examining the vital capacity with electron bronchus lens

目的探讨经电子支气管镜肺活检对肺周围型病变的诊断价值。方法对106例肺周围型病变的患者经电子支气管镜按影像学解剖定位伸入进行肺活检;对尚未能确诊的病例在X线电视透视下重行肺活检。结果按影像学解剖定位肺活检确诊76例,阳性率71.7%;对尚未确诊的30例在X线电视透视下重行肺活检获得确诊18例,阳性率60.0%;共确诊94例,总确诊率88.7%(其中肺癌56例,炎症38例;肺癌占59.6%,居首位)。结论经电子支气管镜按影像学解剖定位肺活检术操作方便,合并症少、安全性大,可避免射线对操作者影响,对肺周围型病变具有实用的诊断价值。

Objective To probe into the value of diagnosing the peripheral type of lung pathological changes by examining the vital capacity with electron bronchus lens. Methods. We examined the vital capacity of 106 patients suffering the peripheral type of lung pathological changes with electron bronchus lens according to the image anatomy orientation inset, and to re-examine the vital capacity of those cases that could＇t form correct diagnosis under the clairvoyance of X-ray television. Results. According to the image anatomy orientation inset, the positive rate was 71.7% （n=76）. By re-examining the vital capacity of 30 negative cases under the clairvoyance of X- ray television, the positive rate was 60. 0% % （n=18）. The overall accurate diagnosis rate was 88.7% （n=94）. Among them, there＇re 56 cases of lung cancer and 38 cases of inflammation. The rate of lung cancer was topped at 59. 6%. Conclusion The operation of vital capacity examination by electron bronchus lens according to the image anatomy orientation inset is convenient, safe, and less complicating. It can avoid operator from the affecting of rays. It has a practical value in treating peripheral type of hinge pathological changes.
